Today, the IAQ Video Network and Cochrane & Associates announced the release of their latest educational video. Their newest production discusses the importance of respiratory protection for workers in various industries. “OSHA reports that an estimated 5 million workers are required to wear respirators in 1.3 million workplaces throughout the United ...

Original story at MIT News Whether intentionally set to consume agricultural waste or naturally ignited in forests or peatlands, open-burning fires impact the global climate system in two ways which, to some extent, cancel each other out. On one hand, they generate a significant fraction of ...

LEED testing for indoor air quality is made simple by California’s dedicated environmental laboratory network. The U.S. Green Building Council (USGBC) established criteria that became a primary tool in rating and certifying new and existing building structures. An official LEED certification increases the value of the property as operational costs of the facilities are usually much lower. ...

This test method covers the determination of the organic fiber content of asbestos-cement products. Three apparatuses shall be used: sieve; drying oven; and an apparatus for determination of total carbon by direct combustion. Hydrochloric acid should be used as a reagent. A calculation shall be made to determine the organic fiber content. Repeatability of the mass of organic fiber ...

Heat transfer fluids degrade when exposed to sufficiently high temperatures. The amount of degradation increases as the temperature increases or the length of exposure increases, or both. Due to reactions and rearrangement, degradation products can be formed. Degradation products include high and low boiling components, gaseous decomposition products, and products ...

This test method is necessary because of the need for rapid reliable tests for carbonaceous material in waters and sediments. It is used for determining the concentration of organic carbon in water that comes from a variety of natural, domestic, and industrial sources. Typically, these measurements are used to monitor organic pollutants in domestic and industrial waste water. When a ...

This test method provides a method of measurement of distillation range of volatile organic liquids. The relative volatility of organic liquids can be used with other tests for identification and measurement of quality. Therefore, this test method provides a test procedure for assessing compliance with a specification. This ...

This test method can be used to establish manufacturing and purchasing specifications. It can also be used to determine the condition of solvents in use. 1. Scope 1.1 This test method covers the determination of acidity in halogenated organic solvents and admixtures thereof. The alkalinity ...

BELECTRIC, the global market leader (2010 & 2011) in the development and construction of ground-mounted solar power plants and roof-mounted photovoltaic systems, has taken over Konarka Technologies GmbH. The group was the leading manufacturer of “Power Plastic,” a thin, film-like organic photovoltaic material with a low weight and a wide range of uses. The German subsidiary of the ...

Two winners in Maine were recognized today at EPA’s 2015 Environmental Merit Awards ceremony. The environmental leaders were among 27 recipients across New England honored for helping to improve New England’s environment. Each year EPA New England recognizes individuals and groups in the six New England states who have worked to protect or improve the region’s environment in ...

Monitoring changes in microscopic organisms called diatoms can assist in evaluating the quality of water over an entire river watershed. Researchers from France have developed a new index that could help Member States fulfill the EU's Water Framework Directive 2000 (WFD). The WFD aims to achieve good ecological and chemical status in surface water bodies by the year 2015. Diatoms are a type of ...

Tests of the type described in this practice may be used to evaluate the corrosion resistance of organic coatings on metal products exposed to highly salty environments, such as areas subjected to deicing salts or coastal areas. Exposure conditions are complex and changeable. ...

When the properties of materials are not fully understood, as with nanomaterials, how can they be adequately tested? A new study has found that two commonly-manufactured nanomaterials can damage human DNA. This highlights the need to evaluate the risks they might pose and design appropriate safety tests. Materials that damage DNA can cause human cells to mutate, which can eventually lead to ...

NMi VSL has enlarged the organization of PT schemes to the measurement of volatile organic compounds (VOCs), normally determined in air quality measurements. We deliver reference samples, certified in house against our primary standards. Ultimately, by participating in PT schemes, labs demonstrate their measurement capabilities. How does it work One PT scheme foresees 3 rounds per year. ...

The US EPA leads Photochemical Assessment Monitoring Stations programs (PAMS) for more than 15 years and many equipments used at PAMS sites are old and need to be replaced. That is why US EPA has conducted a material review of fully automatic GC units able to by analyze the 56 VOC ozone precursors of the PAMS list. They planned to perform an evaluation in two steps : Laboratory evaluation ...

Water quality in rivers is commonly classified according to its physical and chemical properties, but this may not fully describe its biological health. Polish researchers have tested a new method of water assessment, which looks at the toxicity to organisms of not just water, but also sediment and floodplain soil samples. This provides a more complete picture of a river's health and may help ...

Creep, the tendency of materials to deform over time due to applied stresses, has been a focus of the geosynthetics industry since testing first began more than 25 years ago. Creep testing methods have evolved, but the accurate assessment of tension creep (along with transmissivity) remains essential to the product evaluations of organizations considering geomembrane/geocomposite drainage ...

http://www.bbc.co.uk/news/uk-26169373 The water running thigh deep through Ham Sandhu's house in Wraysbury in Berkshire is freezing cold and murky. Floating around in his kitchen is a toy car and a pair of slippers. Clunking gently together near the sink are two rubbish bins. "I brought them in here," he says, "so they didn't drift away." An unpleasant smell thickens the ...

Californiavoters will soon decide whether to require disclosure of the presence of genetically modified organisms (GMOs) in raw and processed foods. If Proposition 37 passes, food manufacturers will be obligated to either add a label stating the presence of GMOs or develop a new formula for their product not containing GMOs, according to the Huffington Post. Additionally, supermarkets will be ...
